Add P3 support to `displayable`

[danburzo]

Hi @ai, thanks for the report.

I think it would be a good idea to have a more general inGamut(mode) -> function(color) method that covers all bounded color spaces. This depends on adding the reference ranges for all color spaces:

• #153

You could then write:

const displayableP3 = inGamut('p3');
displayableP3('color(rec2020 1 0.5 0)');

The term displayable has become somewhat of a misnomer now that the gamut has been extended beyond sRGB. When expressed as color(srgb ...), a color can be displayed even if it has components outside the [0, 1] range.

I like this API 👍
